FEM Analysis on Concrete Columns Confined with CFRP Sheets by ANSYS

Abstract

The use of carbon fiber-reinforced polymer CFRP composites for strengthening and/or rehabilitation of concrete structures is gaining increasing popularity in the civil engineering community. One of the most attractive applications of CFRP material is its use as confining devices for concrete columns, which may result in remarkable increases of strength and ductility as indicated by numerous published experimental results. Despite a large research effort, a proper analytical tool to predict the behavior of CFRP-confined concrete has not yet been established. This project presents the results of experimental and analytical study on the structural behavior of plain cement concrete column, reinforced cement concrete column and plain cement concrete column wrapped with carbon fiber reinforced polymer (CFRP) sheet.
